| description | The energy indicators of multilevel voltage converters are
analyzed. The relevance of the research is indicated by the
increasing demands of technological processes for the economic
use of electric energy, the reduction in power consumed by
semiconductor converters, and also to the level of regulated
reactive power. The converter considered is a five-level voltage
inverter. As the topology of the converter, the structure of the
inverter on H-bridges is considered. The article presents twostage three-phase circuits with the connection of inverter cells to
wye. Possible states of electronic keys and their corresponding
operating modes are described. The voltage of constant voltage
sources is 535 V. In the article algorithms for the formation of
pulse-width modulation (PWM) are considered: Phase Opposition
Disposition, Alternative Phase Opposition Disposition and Hybrid
methods with zero sequence sinusoidal shape of the modulate
voltage or with triangular shape of the modulate voltage. As a
criterion for evaluating the quality of the inverter’s output voltage,
total harmonic distortion and line-to-line voltage are adopted.
A harmonic voltage spectrum is developed for various control
methods of the converter. Possible ways of reducing the harmonic
coefficient, as well as increasing the amplitude modulation factor,
are shown, by using various methods of forming the pulse-width
modulation. |
